The Italian Football Federation has announced it has upheld the 10-month ban of Juventus coach Antonio Conte for failing to report suspicions of match-fixing.
Conte's offence relates to a charge of not informing authorities of possible corruption in two matches involving former club Siena during the 2010/11 season.
The Juventus boss is arguably the highest profile individual to have been caught up in the investigation into the betting scandal which has rocked Italian football.
And Conte's suspension leaves Juventus without a permanent manager just days before the start of the new season and the club's quest to defend their Serie A title.
Reports suggest he will now take the case to Italy's sports arbitration tribunal while Massimo Carrera, a member of Juventus' technical staff, is due to take charge of the first team on a temporary basis.
The football federation panel did, however, reduce the eight-month ban of Conte's assistant, Angelo Alessio, to six months after he had also been found guilty of the same offences.
The panel also affirmed its previous ruling that Juventus players Leonardo Bonucci and Simone Pepe were cleared of wrong-doing.
Defenders Nicola Belmonte of Bari and Salvatore Masiello of Udinese, who were suspected of involvement in fixing a match between the two sides in May 2010, also saw their acquittals confirmed.
